But who is really to blame for the Jets' 3-6 start? I can think of plenty of reasons before pointing the finger at the backup quarterback.

Is it Jets head coach Rex Ryan? Eventually, all decisions pass by the desk of the head coach. Ryan's undying loyalty to quarterback Mark Sanchez has been baffling and his defense has taken major steps backward. Players lashing out also are signs that a coach is losing control of his locker room. Is Ryan the biggest reason for the Jets’ demise?

Or is it offensive coordinator Tony Sparano? The Jets' offense is ranked 30th in the NFL. Sparano has mishandled the Tebow situation and can’t get the offense going. New York was expected to be a physical group but often gets manhandled.

Do you blame Sanchez? The starting quarterback has regressed in his fourth season and has failed to raise the level of his play. Sanchez has not stepped up his game with Tebow behind him. He is on pace for a career-low completion percentage and is making game-changing turnovers.
